An upper-floor structural bay of the Home Insurance Building during late 1885 finishing work, with exposed brick party wall, masonry pier, rough plank deck, metal members and terra-cotta protection visible before office finishes enclose them. The cast-iron column foot bears squarely on the structural deck support, and its bearing head touches the girder underside. The girder's left end sits inside the masonry-pier pocket, and its right end rests directly on the column head. The steel beam's near end seats on a riveted angle at the girder, while its far end enters the rear masonry pocket.

Both gloved hands close around the upper block while pressing it toward the column. Both worker boots meet the plank deck, which lies flat across its supporting floor members.
